SPECIFICATION forming part of Letters Pat No. 782.699, dated February 14, 1905.

Application filed June 30, 1904. Serial No. 214,763.

To aZZ whom, it may concern:

Be it known that LVVILLIAM RICHTER, a citi- 'zen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Heater, of which the following is a full, clear, and exact description.

The invention relates to stoves such'as are used for heating purposes and employing gas, vapors, or other oil fuel; and its object is to proxide a new and improved heater'which is simple and durable in construction and arranged to provide a large heating-surface in a comparatively small space and to produce a proper circulation of the air and thorough heating thereof.

The invention consists of novel features and parts and combinations of the same, as will be more fully described hereinafter, and then pointed out in the claims.

A practical embodiment ofthe invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is aside elevation of the improvement, parts being in section. Fig. 2 is an enlarged sectional side elevation of part of the same. Fig. 3 is a plan view of the same. Fig. 4 is a sectional plan view of one of the tubes and its bottom supporting-plate, and Fig.5 is a perspective view of one of the members of a heating-cell.

In the upper portion of each of the tubes A of a heating-stove using gas or oil as a fuel is suspended a heating-cell B, formed of a plurality of members C, located one above the other, each member being formed of a sheetmetal plate 0, having depending side flanges O and end flanges of which the side flanges are bent inwardly and the side flanges of one plate rest on the upper surface of the next plate below, as will be readily understood by reference to Fig. 2. The plates 0 of the sev eral members C are strung on a rod D, fastened at its upper end by nuts D on a crossbar E, resting on a top plate F, seated on the upper ends of the tubes A and connected by rods F with a bottom plate F bolted or otherwise fastened to the base G of the heater. A burner H for the lower end-of each tube A is secured on a suitable gas-supply pipe H, so that when the gas issuing from the burner is ignited the air in the tube is heated and rises and finally comes in contact with the cell B, which serves to retard the rising of the air and causes a circulation of the air between the several members to insure a high heating of the air before the same escapes at the upper ends of the tubes A.

By reference to Fig. 3 it will be seen that the tubes A are preferably oval in cross-section and the plates C are approximately rectangular in shape, so as to fit the tubes suficiently close to form passage-ways I and I, of which the passage-ways I are between the side flanges U of the plates and the interior face of the correspondingtube A, while the passage-ways 1 are between the end flanges C and the inner face of the tube A. By inclining the side flanges inwardly and downwardly and forming each side flange with a cut-out portion (1* it is evident that the portion of the air rising in one of the side passage-ways I strikes the flanges (J and passes through the cut-out portion C between two succeeding plates C, and air rising in the passage-ways 1 can also pass between successive plates, as the flanges C are considerably shorter than the side flanges C and each end flange C is in addition provided with a cutout portion extending from the bottom edge of the flange to the under side of the plate 0.

The cut-out portion 0 of each side flange C extends from the bottom edge of the flange to within a distance of the under side of a plate C, so as to somewhat confine or hold the air under a plate O to cause the air to pass out through an opening G into an end passage 1. The portions 0 of the lower edges of the side flanges C are beveled to form with the top face of the plate U of the next member C below an opening leading to the cut-out portion C to insure the gradual circulation of the air toward the cut-out portion (1*.

From the foregoing it will be seen that by the arrangement described the heat rising in a tube A is retarded by the members C of the heating-cell, and the heat is also expanded between the plates 0 of adjacent members, thus causing a perfect circulation of the air between the members to insure a thorough heating of the members.

By making the depending end flanges C of each member 0 short and terminating the same a distance above the plate C of the next member (1 below suflicient openings are provided for the air to circulate freely between adjacent members and in a transverse direction relative to the tubes A.

The side flanges U of the lowermost member C (see Fig. 1) are curved outwardly to abut against the inner surface of the tube A to hold the entire cell against lateral ITIOVG" ment, thereby preventing all rattling and jarring of the cell in the tube A.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a heater for burning or oil a heating-cell consisting of a plurality of superimposed members, each having a plate of an approximately rectangular shape, side flanges extending integrally "from the said plate and butting on the plate of the next member to space the members apart, and end flanges extending from the plate and terminating a distance from the plate of the next member.

2. In a heater for burning gas or oil a heating-cell consisting of a plurality of superimposed members, each having a plate of an ap proximately rectangular shape, side flanges extending integrally from the said plate and butting on the plate of the next member to space the members apart, the side flanges being inclined inwardly, and end flanges extending from the plate and terminating a distance from the plate of the next member.

3. In a heater for burn-ing gas or oil a heating-cell consisting of a plurality of superimposed members, each having a plate of an approximately rectangular shape, side flanges extending integrally from the said plate and butting on the plate of the next member, the said flanges having cut-out portions, extending from the bottom edge to within a distance of the plate, and end flanges extending fromthe plate and terminating a distance from the plate of the next member, the end flanges having cut-out portions.

4. In a heaterfor burning gas or oil a heating-cell consisting of a central suspending-rod and a plurality of superimposed members held on the said rod, each member having a plate of an approximately rectangular shape, side flanges extending integrally from the said plate and butting on the plate 01 the next adjacent member, the said side flanges holding the members spaced apart, and end flanges distance from the plate of the next adjacent member.
